Hello and thank you for this sweet app, v5.1. I would like to propose a problem. Issue: When I increased the font size my phone got stuck in a boot loop and I had to flash, at least that's what I did, to get back to normal behaviour. Issue: After the reflash the quicktweak app v5.1 does no longer work. It's reinstalled but does nothing when activating the icon. I have tried several time to uninstall and install, reboot etc. but nothing seems to bring any solution. I have tried installing the v5 but it's the same reaction - none. I would really like a solution - Help! :-) My device has PR1.2.
